This a loose Voyager Lio Convoy (No, I'm not calling him "Leo Prime," because he's not a Prime) from Transformers Legacy: Evolution. He comes with his shoulder guns, however I am unable to find the instructions. If I do find them, I will update the listing.

This figure is reasonably accurate to his appearance in the anime Beast Wars II, though the beast mode's realistic head more evokes IDW's 2006 Beast Wars comic The Ascending.
